Boiler Repairs Questions & Answers

We understand you've got questions about getting your boiler fixed in Aylesford, from costs and timeframes to guarantees and booking the right service.
When it comes to boiler repairs, we're happy to explain everything clearly, including our Gas Safe registration, repair guarantees, and current repair availability.
Our straightforward answers below will help you understand what to expect when you need your boiler repaired in Aylesford.
We service all major brands including Worcester and Vaillant boilers, addressing common issues like low pressure and heating failures.
How much will it cost to fix my boiler?
According to our experience, boiler repair costs can vary considerably depending on the specific issue.
Some quick boiler troubleshooting techniques might reveal a simple fix requiring just an hour of labour, while other problems need more extensive work.
For a typical repair visit, you'll pay for our diagnostic time and any necessary parts.
Simple fixes might only need an hour's labour, but if we're dealing with major components like pumps, fans, or circuit boards, costs can range from £150 to £350 plus labour.
We're committed to providing cost effective repairs whenever possible.
Before we begin any work, we'll always explain what's wrong and give you a clear estimate of the total repair cost.
This way, you can make an informed decision about your boiler repair.
During colder months, you may need to wait up to 2 weeks for repairs due to increased service demand.
How soon can you fix my boiler?
Booking times for boiler repairs depend largely on the season.
During summer months, when we're typically focused on routine boiler maintenance tips and energy efficiency upgrades, we can usually get to you within a day or two. This is actually a great time to address any concerns before the cold weather hits!
However, when temperatures drop and heating demands increase, our schedule gets quite packed. You might need to wait a couple of weeks for an appointment during these busy periods.
That's why we always encourage our neighbours in Aylesford to book early and stay on top of regular maintenance.
For the most up-to-date availability, we've made it super easy – just hop onto our online booking system anytime, day or night, to secure your preferred slot.
Our Gas Safe registered engineers are ready to provide expert diagnosis and repairs when you need them most.
What guarantees do you offer on boiler repairs?
Boiler repair guarantees at Thames Boilers focus specifically on replaced parts, which come with a 12-month warranty covering any defects or failures.
We want to be completely transparent about our guarantee limitations, so you'll know exactly what to expect. If a part we've installed fails within the 12-month period, we'll happily replace it at no cost to you.
However, it's important to understand that repair expectations should be realistic – our guarantee only covers the specific parts we've replaced, not your entire boiler system.
Should different issues arise with your boiler or heating system after our repair, these won't be covered under the guarantee, and additional visits will require payment.
We believe this straightforward approach helps build trust with our customers while ensuring fair service for everyone.
For maximum system efficiency, we recommend combining your repair service with our unvented cylinder maintenance, which includes thorough safety device inspections and pressure testing.
Should I book a boiler service or a repair?
When your boiler isn't working properly, you'll want to make sure you're booking the right type of visit.
While we're often asked about common boiler issues and boiler maintenance tips, there's sometimes confusion about whether to book a service or a repair.
Here's what you need to know: if your boiler isn't working correctly, you should book a repair visit, not a service.
A boiler service is like an annual health check – it's routine maintenance for a working boiler. It won't fix existing problems.
Think of it like your car's MOT versus taking it to the garage when it breaks down.
When your boiler's already showing issues, we'll need to diagnose and fix the specific problem through a repair visit.
Our Gas Safe registered engineers provide expert repairs for all major boiler brands across Dartford, Gravesend, and surrounding areas.
Are you gas safe registered?
Yes, we're absolutely Gas Safe registered and have been since 2002 (formerly known as CORGI registration).
As homeowners ourselves, we recognise how vital Gas Safety is when it comes to your boiler and heating system. That's why we take our Registration Importance seriously – it's not just a legal requirement, it's our commitment to keeping your family safe.

Our expertise is especially crucial during winter months, when households rely more heavily on their gas appliances for heating and comfort.

Common Boiler Problems In Aylesford

In our years serving Aylesford homes, we've seen just about every boiler problem you can imagine, from heating systems that refuse to warm up to combi boilers that can't decide between hot and cold water.
Whether you're dealing with mysterious fault codes, dropping pressure gauges, or that frustrating situation where you've got hot water but no heating (or vice versa), these are all common issues we fix daily.
Let's look at these typical boiler problems and what might be causing them in your Aylesford home.
No hot water but heating is working
Throughout Aylesford, homeowners commonly face the frustrating issue of having working radiators but no hot water from their taps.
It's one of the most common heating issues we encounter, and we've got some helpful boiler troubleshooting tips to share with you.
If you've got a combi boiler, the culprit is usually either a faulty flow switch or a stuck diverter valve.
For those of you with conventional boilers, we typically find it's down to a faulty motorised valve.
While these issues might sound complex, they're actually quite common and something we fix regularly.
The good news is that once we identify which component is causing the problem, we can usually get your hot water running again quickly and efficiently, so you won't have to endure those cold showers for long.
Hot water is working, but radiators are not heating up
Another common heating issue we encounter in Aylesford is when your hot water taps work perfectly, but your radiators remain cold.
During our radiator troubleshooting visits, we often find this problem has a few possible causes you can check before calling us.
If you've got a combi boiler, it's usually down to a stuck diverter valve that's not directing hot water to your heating system properly.
For conventional boilers, a faulty motorised valve is typically the culprit.
But here's something you can check right now: make sure your programmer is actually set to turn the heating on, and your room thermostat is turned up high enough.
We've lost count of how many times we've solved this problem with just a quick adjustment of these settings!
Boiler Pressure gauge keeps going down
Dealing with a constantly dropping boiler pressure is one of the most frustrating issues we see in Aylesford homes.
We understand how worrying it can be when you keep having to top up your system, but don't panic – there's usually a straightforward explanation.
In our experience, the most common cause is a leak somewhere in your heating system.
Our troubleshooting tips start with checking your pressure relief valve outside – if you notice water dripping, that's often your culprit.
We also recommend looking for small leaks around your pipes and radiators. Sometimes, it's not even visible to the naked eye!
Another possibility is a faulty expansion vessel, which we can quickly diagnose during a visit.
If you're in Aylesford and need help getting to the bottom of your pressure problems, we're here to help.
Hot water on combi boiler runs hot and cold
Getting inconsistent hot water temperatures from your combi boiler is a common frustration for many Aylesford homeowners.
When you're trying to enjoy a nice shower or wash the dishes, it's incredibly annoying to have the water temperature fluctuating between hot and cold.
When it comes to troubleshooting hot water issues like this, we often find two main culprits.
The most common cause is a blocked plate heat exchanger in your combi boiler, which prevents proper heat transfer to your water.
If you're only experiencing this problem with your shower, though, it's likely a faulty shower cartridge that needs replacing.
We're here to help identify and fix these combi boiler issues, ensuring you get back to enjoying consistent hot water throughout your home.
There's a fault code on my boiler
Fault codes on your boiler's display can feel like a cryptic puzzle when they suddenly appear. While these error messages might seem intimidating at first, they're actually your boiler's way of telling you what's wrong – think of them as your boiler's language for communicating problems.
When you're faced with fault code troubleshooting, we recommend a simple first step: do a quick online search with your boiler's make and the specific code (for example, "Vaillant F75"). This can give you a better understanding of what you're dealing with.
However, while it's helpful to understand what these boiler error messages mean, we always advise against trying to fix them yourself. As your local Gas Safe registered engineers, we're here to properly diagnose and resolve any fault codes safely and effectively.
Boiler is making a loud banging sound when it turns on
When your boiler starts making loud banging noises during startup, it's often a sign that water isn't circulating properly through your heating system. This issue, known as kettling, can be quite concerning for homeowners in Aylesford, and we recognise why those banging noise causes might worry you.
In most cases, we find this happens when your boiler's pump isn't working correctly, or there's trapped air in your system. Sometimes, it could also mean your main heat exchanger is blocked.
While it might be tempting to ignore these sounds, they're actually important boiler maintenance tips to pay attention to. We always recommend getting these noises checked out promptly, as they can lead to more serious problems if left unaddressed.
At Thames Boilers, we're here to help diagnose and fix these issues before they escalate.
